8. AGGREGATE IMPACT VALUE TEST (IS 2386 – PART – 4)
Object: To determine the toughness of road stone materials by Impact test
Apparatus: Impact testing machine, Measure, Tamping rod, Sieve, Balance, Oven
Procedure:
Take the oven dry aggregate
Collect the agg. Material Passing From 12.5 mm to 10 mm
Cylindrical Cup
Give the stroke by Hammer
Material pass mm sieve

9. Aggregate Impact value Test
Sr. No.
Details
Trial Number
Average 1 2
Total Weight of aggregate sample filling the cylindrical measure = W1
Weight of aggregate passing 2.36mm sieve after the test = W2 3
Weight of Aggregate retained on 2.36mm sieve after the test = W3 4
W2 = W1 - W3 5
Aggregate Impact Value = 100 W2/W1 percent

10. F.I &E.I TEST
Object: To determine the flakiness and elongation of the aggregates by standard flakiness gauge and elongation gauges. Apparatus: a) Flakiness gauge (Thickness gauge):The Flakiness index of aggregates is the percentages by weight of particles whose least dimension is less than three-fifths (0.6) of their mean dimension. The test is not applicable to sizes smaller than 6.3mm b) Elongation gauge (Length gauge): The elongation index of aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than one and four fifth times (1.8) their mean dimension

11. Cont..
Procedure
a) Flakiness Index: The sample is sieved with the sieves mentioned in table. A minimum of 200 pieces of each fraction to be tested is taken and weighed. In order to separate flaky materials, each fraction is then gauged for thickness on a thickness gauge. The amount of flaky material passing the gauge is weighed to an accuracy of at least 0.1percent of the test sample.
b) Elongation Index: The sample is sieved through the IS sieves specified in table. A minimum of 200 pieces of each fraction is taken and weighed. In order to separate elongated material, each fraction is then gauged individually for length in a length gauge. The pieces of aggregates from each fraction tested which could not pass through the specified gauge length with its long side are elongated particles and are collected separately to find the total weight of aggregates retained on the length gauge from each fraction. The total amount of elongated material retained by the length gauge is weighed to an accuracy of at least 0.1 percent of the weight of the sample.

14. WMM MIX DESIGN Impact value test Shape test Water absorption
Scope of Design: To determine design percentage weight mix of mineral aggregates at desired density and % O.M.C, a series of test specimen are prepared.
Coarse aggregate mm to 22.40mm-Sample-A
Coarse aggregate mm to 11.20mm-Sample-B
Coarse aggregate mm to 4.75mm-Sample-C
Stone dust mm down size -Sample-D
Determine the physical properties of above sample

23. Construction Procedure Flexible Pavement
There are mainly five important layer of pavement are constructed which are as follows
Soil Sub Grade
Granular Sub Base
Wet Mix Macadam
Dense Bituminous Macadam
Bituminous Concrete

24. SOIL SUB-GRADE
Soil sub grade is one of the important layers of pavement because whatever load comes from the top layer ultimately it will transfer to soil sub grade. So soil sub grade is one of the important layers. The soil Sub grade is a layer of natural soil Prepared to receive the layers of the pavement materials placed over it.
Construction of soil -sub grade
Construction of soil -sub grade

25. CONSTRUCTION PROCEDURE
Cleaning and grubbing of the area
Filling of extra excavation portion
Wetting of surface by means of water sprinkling and finally rolling is to be done
Compaction
Take the field density
Calculate the CBR value
Construct GSB.

26. GRANULAR SUB BASE
Granular sub base is also known as (GSB), which is above the soil sub grade. This layer is also constructed after 24 hrs of construction of soil sub grade. Soil Sub grade layer require hard. GSB. consist of Mixing and laying of hard Murum soil, aggregates, stones, Bricks, water The thickness of GSB layer 150 mm

27. CONSTRUCTION PROCEDURE GSB.
Preparation of soil sub grade construction of sub base can start after 24 hours of construct the Soil Sub Grade
Mixing and laying of hard Murum soil, aggregates, stones, Bricks, water
Compaction by means of roller is to be done and its in 7 pass
Find Out FDD (Field Dry Density)
 Find out Soil Strength by CBR Test
Then construct WMM Layer

28. Asphalt Drum Mix Plant
A HMA plant is an assembly of mechanical and electronic equipment where aggregates are blended, heated, dried and mixed with binder to produce HMA meeting specified requirements. The plant may be stationary or portable
There are numerous types of plants, including batch plants, continuous mix plants, parallel-flow drum plants, counter flow drum plants, and double barrel drum plants to name a few.
